ing spouts the containers, said units be 55 are inserted into twocontainers at the same time, one spout being inserted into eachcontainer by of the guideway through which the spout is projectedbetween the dies 15 and [6 so as to receive the completed spout as thelatter is severed from the strip [1.

A pushenjor rain 41 is slidable in the channel to push the severed andcom leted spout through the channel and through the slits or scores inthe bottom 'wall 43 of the container. The pusher 41 maybe of anysuitable construction, but as shown comprises a bar of a cross-sectionapproximately, corresponding to the sha e of the channel 46 andconnected to a guide block 48 that is slidable in a correspon inglyshaped opening 49 in the scout holder. The ram 41 is actuated upwardlyby a roller 50 carried by the guide block 48 and riding in a cam slotwhich'is mounted in a plate 52 connected to the slide block 2 of thespout-forming mechanism, said roller 50 being caused to ride upwardly inthe cam slot 5| (see Figures 4, 6 and 7) when the spout-inserting unitsare moved synchronously with the containers.

This synchronous movement of the spout-inserting :mechanism with thecontainers is effected by abutment blocks 53 mounted exteriorly on thelower end of the turret 3 cooperating with pawls 54 which are pivotedintermediate their ends 55 on the auxiliary frame 45. These pawls 54 arenormally located as shown in Figures 6, 9 and so that the rear endsthereof will be abutted-by the blocks 53 so as to swing the frame 1 45and the spout-inserting units with the turret. It will be observed thatthe abutment blocks and pawls will be so located on the machine that thespout-inserting mechanism will be moved with the turret only when acarrier 6 with a container thereon is properly juxtaposed to and aboveone of the spout-guiding channels 46, and that the movement of thespout-inserting mechanism with the turret and containers will continueonly long enough to permit the rams 41 to push the spouts through therespective channels 48 into'the bottom walls of the containers.

To interrupt or stop the movement of the snout-inserting mechanism withthe turret, a fixed cam 56 is mounted on the frame piece 32 to beengaged by the leading end of the correabutmentblock 53 as shown inFigure 10.

The reversing of the spout-inserting mecha- I -nisrn is effected by arotating cam 58. which co- :operateszwith a roller or hearing block 59on the auxiliary frame 45 (see Figures land 9)}said cam being mounted onthe shaft 3| and being driven gin timed relation to --the turret 3. Thiscam has a shoulder 60 followed by a concentric dwell 6| for moving andholding theauxiliary frame 45 in its normal position in properrela-Ition to the spout-forming mechanism, the cam {also having a cut-awayportion 62 which pro- -vides a clearance to permit movement of theauxiliary frame 45 with the turret during the spout-inserting operation.

IT? From the foregoing, it will be understood that the spout-blankstrips I! will be forwarded, step bystep, two spouts will be completedin the dies and I6 upon movement of the slide blocks -23 and die l6 bythe cams from the positions "shown in Figures 4 and 5, to thepositionfjshown in Figures 7 and 8, and a completed spout will be?severed from the strip and depositedin each spout-receiving channel 46.Then, when a conftainer is in proper juxtaposition above each While inall cases it is not essential, generally .spout-receiving channel,

-rnechanism will be moved synchronously with the containers by theblocks 53 and pawls' 54; and,

the spout-inserting simultaneously, the rollers 50 will ride in the earn2 slots 5| so as to actuate the rams 4'! upwardly to insert the spoutsthrough the bottom walls .43

ofthe respective containers as shown in Figure 8. It will be understoodthat the prongs l3 will also be forced through the walls of thecontainers and will be clinched as shown in Figure 8 by engagement withthe lower end of the corresponding carrier 6 under the pressure of theram 41.

it is desirable to preliminarily score or slit the .Iwalls of thecontainers to facilitate insertion of "the wings of the spouts throughsaid walls. For

this purpose I have shown two identical slitting units 63 mounted on theauxiliary frame 45 in spaced relation to each other, corresponding to"the spacing of the container carriers 6, so that 7 while two spouts arebeing inserted, one in each 'of" thetwo containers, slits will be formedeach of two succeeding containers.

As shown, each slitting unit comprises a body portion 64 secured by abolt 65 on the auxiliary 'frame and has a-slide block 66 verticallyslid- "able therein. This block 66 carries a follower roller 61 whichrides a cam slot 68 in a plate 69 that is mounted on the frame piece 32.

Mounted on the top of the block 66, is a blade carrier 10 which has twoblades H so shaped and arranged as tov form the desired slits in thecontainer wall in cooperation with slots 12 in ;the lower end of thecorresponding carrier 6 see i Figure 14).

The blade carrier 10 is adjustably "mounted in a groove 13 in the block66 by set screws 14 which abuttingly engage upwardly converging sidewalls 15 on the blade carrier, and ..the blade carrier is verticallyadjustable by a 'wedge plate 16 which engages a beveled surface "ill onthe block 66 and is held in adjusted posi- ;tionby a cap screw 18. 1

With this construction, assuming it is desired to elevate the bladecarrier 10, the set screws "14 will be loosened and the cap screws 18will be tightened so as to force the beveled sides 15 .of the carrier 10into tight engagement with the screws 14. To adjust the blade carrierhorizontally, one screw 14 may be loosened and the other tightened. Itwill be understood that when the auxiliary frame 45 moves with theturret 3.

the rollers 61 will ride in the cam slots 68 so j i-as to first forcethe blades H against the bottom walls of the respective containers, andthen per- .mit the blades to withdraw; and the slitting mechanisms arelocated in advance of the spoutinserting mechanism so that thecontainerwalls will be slit or scored prior to their presentation to thespout-inserting mechanism.

The preferred form of container carrier comprises a body portion I9 of across-sectional shape and length to receive the container to be operatedupon, and at one side of the body portion I9 is mounted a containerholder which comprises a spring strip 80 secured at one end to a pivotblock BI that is pivotally mounted at 82 onthe body portion andisconnected by .a link .83 to a slide rod 84 whichisslidably mountedina'horizontal circumferential flange 85 on the turret, from which thecarriers 6 are suspended. The slide rods are normally influencedupwardly .by compression springs 86 so as to swing the spring strips 80into a position to tightly frictionally engagethe container slipped overthe "carrier as shown in Figure .12 and thereby hold the containeron-the carrier. 'eontainerfapplying station I .and the container-However, at the removing station H, this slide rod is pushed downwardlyby engagement of. a roller BI-Witha eam'track BB-on the top plate'2 soas to'swing the spring'strip '80 into the position:shown in Figures 13and 18 so that a container may .b

easily slipped on or ofi the carrier.

Forautomatically applying the containers to the carriers 6, Iutilize ahorizontal table 89 which is iournaled on a vertical shaft 99 in abearing bracket 9I'that issecured to the pedestal I,1said table having aplurality of pockets 92 of across- -sectional shape approximatelycorresponding to that of'the container being handled, :and of.suflicient size to permit the containers 'to be easily dropped into thepockets, eithermanually or automatically, from a conveyor.

.The table is rotated by bevel gearing 93 from a countershaft 94 whichis connected by bevel gearing '95 to a'vertical jackshaft 96 that'isgearedat 191 to the internal gear 34-at the bottom of the turret. Thetable is so mounted that the pockets '93-are moved in continuoussuccession beneath .the table 89-approximately co-axially with eachpocket 92, the lower'end of each push 'rod99 having a roller I99 which,when the correspond.- ing pocket is in alignment witha carrier 6 passesoverone end of a lever IIII which is pivotally mounted intermediate itsends at I02 on the bracket? and has a-roller I03 at its other endthat'fol'lows a cam I04 on the bottom of the table 89. The cam IN is soshaped that as each push rod 99 arrives over the end of the lever IN,the lever is swung upwardly to pusha container upwardly onto the carrierdisposed .above the corresponding pocket.

The practical extent of movement of the pusher plate 98 isnot'sufiicient to slide the container entirely upon the carrier, and tosupplement the action of the pusher plate, I utilize a three-armedlifter I05 which is carried by a horizontal shaft I06 that has a bevelgear connection III! with a vertical'counter-jack-shaft IE8 which isgeared rrler and the pusherplate 99'that as the latter "moves frombeneath the container, one'arm of the lifter engages the bottom wall ofthe -container as shown in Figure 19, andupon further 8 rotation of boththe carriage 3 and the lifter, the container i pushed all the way ontothe corresponding carrier.

As hereinbefore described, during this'application of the container, thecontainer holder is in the position shown in Figure 18, but after thecontainer has been slipped entirely upon the carrier, the holder 89 isreleased by the cam track 88 so that it may firmly frictionally grip thecontainer to hold it on the carrier.

In accordance with the invention, the containers are also automaticallyremoved from the carriers after the spouts have been inserted, and forthis purpose I utilize a mechanism which is'illustrated in Figures 21and 22 and comprises an approximately horizontal arm I I I that ispivotally mounted at one end at I I2, on a bracket II3 that is rigidlysecured to the top plate 2. This arm is normally influenced upwardly bya spring H4 so that it 'is disposed above the top edge of the containerson the'ca'rriers as shown in Figure 21, and is so located that it willenter between the carrier and the hinged top wall N5 of the container asthe container is rotated by the carriage.

' When the top edge of the container has'moved beneath the arm III, thelatter is swung down wardly into the position shown in Figure 22 so asto forcibly slide the'container ofi the carrier. This action is effectedby a link I I 6 which pivotally connects the arm I II to one end of alever III which is pivoted intermediate its ends H8 011' the bracket H3and has a roller H9 at said end to cooperate with cam lugs I29 on theupper edge of the turret or carriage 3. There is one lug for eachcarrier, and as the lug passes over the roller H9, the link H6 is pusheddownwardly to swing the lever I I I downwardly and force the containerfrom the carrier. If per chance the spring H4 fails to return the leverI I I, the lug will strike another roller I2I at the opposite end of thelever I II so as to forcibly swing the arm I I I upwardly.

-While I have shown and described the invention as embodying certaindetails of construction, it will be understood that this is primarilyfor the purpose of illustrating the principles of the invention and thatmany modifications and changes in the construction of the machine may bemade within the spirit and scope of the invention. Furthermore it willbe evident to those skilled in the art, that the invention may beutilized for inserting or attaching other parts than pouring spouts intoor to other articles than containers, and that other means than theslitting units 63 may be used for performing different operations uponthe containers or other articles.
